Abstract:
The behavior of macroparticles that form a near-wall dust in tokamaks is described with allowance for the force of gravity, force of entrainment by plasma ion flux, and Lorentz force acting on the motion of charged macroparticles in an inhomogeneous magnetic field. It is shown that, in some cases, the effect of induced currents that arise in the particles during this motion must in some cases be taken into account.
